Rated 4.9 Across 110+ Reviews


This oil, soap, and water solution is easy to make and worth the effort if you want to save money and be kind to the environment, while protecting your plants.

It works great for eliminating small soft bodied insects such as aphids and can be used for plants indoors or out including veggies!

There is no nasty residue, it's non-toxic to animals and birds, and doesn't harm beneficial insects if used correctly. It's basically a plant cleaning solution that suffocates specific small bugs that breath through their skin. BONUS: It's good for keeping away some molds, mildews and plant fungi.

3 Precautions to Protect your Plants

1. On delicate plants, test a small portion first.

2. Don’t over-spray in one use, but treat weekly.

3. Only use in under 90° F to avoid burning your plants.

3 Household Ingredients

1. One cup oil (any variety)

2. One tablespoon dishwashing or “pure” soap (without degreaser/bleach)

3 Simple Steps

1. Combine the oil and soap to create a “soap” mixture.
